Specification of Letters Patent.

Patented May 9, 1916.

Application tiled Jane 23, 1913. Serial No. 775,295.

To all whom it may concern:

Be it known that I, Amos CALLESON, a citizen of the United States, residing at Brooklyn, in the county of Kingsand State of New York, have invented certain new and useful Improvemcpts in Filling and Capping Machines, of which the following is a specification.

This invention relates to machines for filling and sealing bottles or the like, and it consists in certain improvements hereinafter set forth in the clauses of the claim whereby the following principal objects are accomplished, to wit: To provide a machine whereby the filling and sealing of bottles may be accomplished with great ex edition and substantially wholly without t e aid of attendants except for introducing the empty botties to and removin" the filled bottles from the machine; whereby bottles may be operated upon which may vary more or less in size, especially in height; and whereby accuracy and efiiciency of operation Will be insured, for instance, so t at uniform quantities of liquid will be delivered to the bottles, waste avoided, and delay or injury to the machine, due to careless handling, prevented.

Other objects will appear hereinafter 1n the following description, which, taken with the accom )anying drawings, explains the preferred orm of the improved machine.

In said drawin s, Figure 1 is a side elevation of the mac line, certain parts being omitted; Fig. 2 is a vertical sectional view of the lower part of the main frame and a rotary structure journalcd therein and forming a frame in which certain of the mechanisms have movement; Fig. 3 is a horizontal sectional view in a plane just above the bottle-feeding table; Big. 4 is a substantially similar view on a larger scale, with said table and certain other parts removed; Figs. 5 and 6 are fragmentary vertical sectional views on lines w-ru and l/, respectively, of Fig. 8, showing one of the bottle-elevating plungers; Figs. 7 and 8 are front elevations of the grip device of said plunger with and without its front late, certain parts appearing in section; ig. 9 is a front elevation of the cover plate of the grip-device; Fig. 10 is a fragmentary. sideelev'ation of-the plunger, the cams controlling the same appearing in section; Fig. 11 is a plan of a bottle-support; Fig. 12 is a horizontal sectional view 1n a plane just above the liquid reservoirs, certain parts being omitted; Fig. 13 is a plan, Figs. 14 and 1.3 end views and Fig. 16 a longitudinal sectional view of a certain block 2; Figs. 17, 18 and 19 are a side elevation, artly in section, a plan and an end elevation of a certain slide 9; Fig. 20 is a fragmentary plan of the uppermost disk of the aforesaid rotary structure partly broken away to reveal the bottle-neck gripping gas kets and their operating means; Fig. 21 is a vertical sectional view of one of said gaskets and a part of its operating means; Fig. 22 is a horizontal sectional view similar to Fig. 12 but including certain parts omitted therein; Fig. 23 is a plan of a system of slides, the race therefor, and their operating mechanism; Fig. 2f shows in fragmentary front elevation and also in vertical section said race and the syrup-filling and master slide groups; Figs. 25, 26 and 27 are a plan, front elevation and vertical sectional view of the main slide of the master group; Figs. 28 and 29 are a plan and front elevation of the auxiliary slide of the master group;

"he stationary frame includes the fixed central shaft a, the pillars b, the base a, ring (l having cam ring d, the part-circular racering e, Figs. 1 and 23, and the head The rotary frame includes the cylindrical pillar q suitably journaled on the shaft a, and the ower disk h, intermediate disk or hood i, and upper disk j, all fixed on the pillar g. All of the operations incident to the filling and sealing of the bottles are performed as the bottles are carried around the shaft (1. in a circular course one after the other. They are started on this course by the means shown at the lower right in Fig. 3, and after undergoing-the filling and sealing operations they are discharged onto the left hand end of a stationary table shown in said figure. The said means and the table will be later described.

\Vhilo undergoing the filling and sealing operations each bottle rests upon one of a circular series of bottle supports In each having an elastic bottle seat l and an upstanding portion m suitably recessed and padded so as to center the bottle on the seat 1 when, as will appear, the bottle is slid onto said support. Each support Z: forms the head of a carrier or plunger which is guided for vertical movement in the disks h and i and which, as the size of the bottle demands, is adjusted in efiective height. Each plunger includes a stem n carrying the suport k and suitably guided in the disks i and and a grip device now to be described in detail.

0 is a block having a vertical groove 7) receiving the stem 72. and having a cover plate 1 covering said groove and certain other parts to be described. and also having an inwardly projecting forked stud r which receives a vertical fin s on the pillar g and so holds the plunger from turning while allowing vertical movement of the grip device. Fiber or other friction plates 6, under the influence of springs u housed in the block 0, establish a slip-friction-grip of the grip device on the stem. As will a ppear, upon the bottle coming to rest on t e support In the plunger is elevated and forces the head of the bottle against a gaging abutment, slippage then occurring as between the stem and the grip-device. When the upward pressure on the plunger ceases the slipgrip as between the stem and grip-device is converted into a positive grip by the clutch means shown in Figs. 5, 7, 8 and 10 as follows: Clutch-rolls u, pressed downwardly by spring plungers w and housed in the block 0, are adapted to become jammed between the side of the stem n and the opposite walls (1:, converging downwardly toward the stem,

' 17 joined by the rise of the recesses containing them and thus bind or lock the stem positively to the gripdevice in a well-known manner. A lever 7 however, fulcrunaal in the block keeps the train of parts r, 10 elevated until their positive locking action is to occur. The means for elevating the plunger and controlling its lever will be later described.

In radial moves 2- in the top of disk j (Figs. 2 and 12) are set blocks 2 (Figs. 13-16) each having a longitudinal interior guideway 3, having a cushion -l (Figs. 45-48) at the outer end thereof, and a longitudinal slot 5 and an orifice (5 penetrating it. The outer top portion of the block is cut away forming part of a beveled shout der 7 (extending clear around the disk y') and, around the orifice. a bottle-cap rest 8. In the guideway is a slide 9 having upward and downward bosses 10 and 11 protruding from the block 2 through its slot. The boss 10 is fitted with a roller 12 and it and the slide have a port 13 which at one end terminates in a nipple 1-t on the boss 10 and at the other opens downwardly at the outer end of the slide. This port may be closed by the downwardly protruding valve 13. The block and slide have also the ports 15 which, when the slide is at its extreme outermost position register to form a vent. The slide forms a part of the means (as will appear) for conveying the liquid to the bottle; it also forms with the other slides means whereby all bottles passing through the machine may have their heads preliminarily established at the same level, thus: One such block and slide are arranged directly above each plunger (supra). A roller 16 on the grip-device of the plunger runs on a camway 17 having a low and a high level, 17. 17 terminating in a slight hump 17 (Fig. 1) and by the fall 17" having the incipient hump 17. "When the Klunger mounts the rise 17 it thrusts the end of the bottle carried thereby against the slide (at this time in its outermost position), slippage of the stem in the grip device of the plunger then occurring until the top of the rise is reached, whereupon the whole plunger falls back somewhat, as it passes from the hump 11' to the level 17. so that the bottle head is just out of contact with the slide. Thus each bottle has its head preliminarily established at a certain level. (All the operations incident to filling and sealing each bottle occur while tlu plunger is passing over the high level 17 and the hump 17, as will appear). A cam way 18, extending parallel with the lov level 17 and rise 17, supports the lever 7 of the grip-device (thereby maintaining it clutch passive) until the roller 16 ha reached the summit of the rise 17, where upon, terminating, it allows the lever to fal and the clutch to become active to positivel hold the stem at the exact relative elevation it has been made to assume.

A circular series of segmental oriliced plates 19 is suitably secured to the under side of the disk each covering and forming a housing with a circular opening 20 which is open at the disks periphery and opens upwardly into one of the grooves 2 (Figs. '2. 20. 4? and 48). An elastic bottlegripping gasket 21 is supported in this housmg by the radially movable blocks 22 each having a dove-tail tongue and groove connection fil -Fig. 48-with the gasket and a radial tongue 24 sliding in a suitable groove in the plate 19, and the series of blocks may be contracted, to contract the gasket, by a rotary ring 25 having inward cam-pro ections .26 bearing against rollers 27 on the blocks and an outwardly projecting rollercarrying arm 28 held against the cam-rin (1 on the ring (I by a spring 2%). The neck of each bottle, when elevated as above stated, is thrust through gasket 21, whereupon at the proper stage the gasket is contracted into gripping relation with the bottle due to the Mug 2?) being turned against the tension of its spring .29 by the cam-ring rZ'. By this operation the ottle becomes exactly centered on the support In relatively to the filling and other subsequently acting ap iliances.

'lhe race ring 0 is suitably secured to the four pillars b and on it are arranged to slide the master slide 30 and the syrup charging and sealing head slides 31 and 32, the three being connected by the adjustable links 33 so as to slide all together. Arranged to slide on the master slide is the auxiliary slide 34 and suitably guided in the slides 31 and 32 are the vertically moving slides 35 and 36. ()n a vertical stud 37 on the slide 31 is fulcrumed a bell crank lever 38 having one arm connected by the link 39 with the auxiliary slide 34 and the other arm connected by a llexible link 40 with one arm of a bell crank lever 41 whose other arm has a pivoted bearing piece 42 arranged to play back and forth in a horizontal slot 43 in the slide 35; the slide 36 is moved up and down by a cam lever 44 fulcrumed in the slide 32 and which, when turned to the left in Fig. 3:), bears down upon a roller 45 on the slide, and, when turned to the right, wipes its stud 44" against an overhanging shoulder 46 on the slide, said lever being connected with slide 34 by the link 47. As the train of slides is moved back and forth on the race, the slide 34 is reciprocated on the master slide 30,

the ditl'erential movement thus occurring being caused by two levers 48 and 49 fulcrumed on a suitable stationary shaft 50, having teeth to respectively intermesh with gear teeth on the auxiliary slide 34 and master slide 30 (Figs. 23 to 27) and oscillated back and forth by pairs of cams 51 and 52 each wiping against the inner sides ol a pair of rollers 53 on each lever, the cams being carried by a suitably journaled shaft 54. Due to the ditl'erential movement, as the slides 31 and 32 reciprocate, the slides 35 and 36 move up and down.

Turning, now, to the syrup charging means. the liquid filling means, the closure allixing means and the closure supplying means, and lirst to the syrup charging means: The slide 35 (Figs. 32, 33. 34 and 47) carries a reservoir constructed as follows: is a cylinder secured to the slide and having screwed into its lower end the threaded sleeve 56 through which extends the tubular stem of a plunger 57 having its head arranged in the cylinder, said plunger carrying at its lower end a nozzle 58 containing a spring 59 which presses a valve no upwardly against the lower end of the plunger and normally prevents the escape of the syrup contained in the cylinder. The cylinder maybe supplied with syrrp from any suitable source by a tubular connection (31 attached to a removable plug 62 forming the top of the cylinder. After the head of the bottle has been elevated and gaged at the proper level by the slide 9. then descends slightly. and then becomes gripped by the gasket 21. the slide 9 is retracted by means to be explained. As the bottle proceeds on its rotary course the syrup charging slide advances with it for a certain distance and at this time the auxiliary slide 34, moved faster than the train of slides 30, 31 and 32 through the connections 39, 38, 40 and 41, forces downwardly in the slide 31. the slide 35; the nozzle 58 is checked in its downward movement by the bottle into whose mouth its reduced lower end (Fig. 47) is thrust, and as the cylinder continues the downward movement the resulting pressure upon the contained body of syrup forces open the valve (30 and allows the syrup to enter the bottle. When the slide 35 rises a fresh quantity of syrup enters the cylinder. restoring the plunger to its normal position. The amount of syrup in this way dispensed to each bottle may be varied by adjusting the capacity of the cylinder by screwing the sleeve 56 inwardly or outwardly in the cylinder to vary the distance between the head of the plunger and the plug 62. If there should be no bottle present the nozzle would be projected through the gasket without opposition and consequently no syrup would flow.

The filling means will now be described: On a collar (38 secured on the shaft (1 above the disk 1' is fixed the bushing 64 having on one side the lilling-liquill-conducting and airescape channels 64" and 64. respectively, and on the other side the filling-liquid-conducting and gas-pressure channels (34 and 64,

res iectively, each channel extending partial y around the bushing as shown est in Fig. 39; the channels 6-! and 64 have leading-in ports 64" and 64 formed with suitable ni )ples 65 and 66, respectively, and the channel 64" has an outlet port 64 ending to atmosphere. Betweenadjustablescrew-rings (\T on this bushing is journaled the body part ()8 of the liquid reservoir supporting structure, the same having upstanding from said body part the trans arent glass cylinders 9 arranged in a eirc e and each surmounted by a head into which is screwed a hollow threaded sleeve 71 through which extends the hollow stem of 'a piston 72 confined against vertical movement (though rotutive) relative to the sleeve by its piston head and a nut 73; by turning the sleeve in the head 70 the piston is raised or lowered, changing the capacity of the reservoir formed by the cylinder and its adi'nncts. 'lhe littings 71 and 72 atlord hand es for ell'ectiug the relative rotation of parts 71 and T2. The piston has suitably attached thereto a float 7% which, when 0 evatcd by liquid in the reservoir, forces a valve 75 upwardly into closing relation to the ort of the piston. For each reservoir suit structure has a port 68 leading from its inner surface in the horizontal plane of channel 6% to the interior, of the reservoir; a port 68 leading from said reservoir to the inner surface of said structure in the horizontal )lanoof the channel 64;"; a ort 68 connectmg the inner surface of said structure in the horizontal plane of the channels 6-1 and 64" with a nipple 76 which is connected with the fitting 79." by the flexible tubing 78; and a port 68 (Figset and 47) leading from the inner surface of said structure in the horizontal ilaneof channel 64 to an exterior nipple 9 onto which the nipple 14 (Figs. 17 19 and 47) is'fitted a flexible tube 80. Flexible tubes 81 and,82, attached to thenipples 65 and 66', are respectively connected to suitable filling-1i uid 'an gaspressure sources (not shown The reservoir structure is coupled with the disk j so as to rotate therewith by one or more osts 83 (Figs. 12 and 47) fixed in each of t em. While each reservoir is passing through approximately one-half of the cycle the filling iquid enters the reservoir via 81', 64", 6t, and 68, the air in the reservoir escaping via 72, 78, 68, 64", and 64 the liquid flow stops when the valve 75 is raised to its seat by the rising liquid. When the reservoir is passing through approximately the other half of the cycle the liquid charge in the reservoir escapes via 68", 64, '80, and port 13 of the slide 9 to the bottle under gas pressure admitted to the reservoir via 82, 64="',64, 68; 78 and 7 2. A valve'is thus produced by the parts 64 and 68. The a sealed-chamber condition around the manner of preserving.

bottle month during filling and of venting the air in the bottle at that time will be explained later. A yielding thrust-piece 84, carried by each bottle support k, is adapted, should no bottle be present on the support, to elevatethe valve 13' and so cut oil the discharge of the liquid through port 13 of slide 9 and prevent waste in that case.

The closure-allixing and closure-supplying means will now be described.

he slide 36 forms a vertical hollow stem into the lower end of which is screwed the thimble S5 guiding and forming a seat for the plunger 86 pressed downwardly there against by a spring 8? bearing upwardly against a plug 88 screwed into the stem. The lower end of the plunger normally protrudes into a scaling device 89 (cylindrical in form so that when a closure surinounting a bottle head is forced u i into the same its flange will be contractor into locking engagement with the shoulder on the bottle in a well known manner) held between the thimblo and the interior llange of a cap 8 having its lower face stepped (Figs. an and 47) and provided with a stepped elastic gasket 89 to conform with the top surface of each block 2 as at 7 thereof.

The closures (ordinary crowns or the like) are supplied from a suitable hopper 90 Figs. 1 and 45 to its chute 91 whose lower end is deflected toward and terminates close to the shoulder 7 on the disk 7'; the hopper is provided with any suitable means for discharging the closures in properly faced disposition, the same in the present instance having the rack 92 for operating its moving parts. As the disk j rotates, the lowermost closure in the chute wipes against the shoulder 7 until it reaches an approaching recess forming the rest 8-when, if otherwise free to do so, it is forced by those behind onto said rest, clear of the chute. The closures are thus one after the other transferred from the chute to the disk 70, each assuming a position on the disk directly above the mouth of the bottle, if present. If no bottle is present it is desirable that no ca. or closure should be fed to the correspont ing rest 8, since otherwise the cap, remaining on its seat until the syrup charging means is reached, would cause the latter to waste a charge of syrup and foul the parts. A detector lever 93 (Fig. 46) is therefore pivoted in the ring d adjacent to the chute 91 and is held projecting into the path of the upward rise of the bottle by a spring M connecting a rod 95, pivoted to said lever, with the chute. A detent lever 96, fulcrumcd in the chute and pivotally connected to the rod, is normally held by the latter in obstructing relation to a train of closures in the chute; but if a bottle is present and, in passing, shifts the lever 93, the detent lever releases the train of closures so that lit the lowest closure will be free to seat-itself" on the disk j as soonas the next rest 8 approaches.

Each slide 9 in one complete cycle of the disk performs twoinward and outward radia movements;-it moves to the outward position, first, so as to be in osition (as described), to servens a gage 1n cooperating with the compensating bottle elevating means; it then returns to the'inward position so that the o ening 6 through the block 2 is unobstructed for the descent of the nozzle of the syrup charging means it thenmoves to the outward position again so as to bring the discharge end of its ort '13 over the mouth of the bottle, 2'. e., t is position it occu ies when the filling-liquid is fed to-the bott e; it finally returns to its inward position so as again to leave unobstructed the opening 6 through the block 2 for the rise of the bottle neck incident to the closure affixing operation. For producing these movements of each slide 9 a suitable camway 97, receiving the roller 12 on the slide, is formed between the-sinuous eriphery of a disk 98, secured on shaft a etween the parts j and 63, and two diametrically opposite yokes 99 (Figs. 12, 45, 47 and wksecured on the ring (1 and overhanging :The means shown; at the lower right of Fig. 3, and-also in "Fig. 1, for delivering thezbottles one after the other onto the bottle supports it includes a thindisk 100 arranged above the table 101 soas just to overlap each bottle support as it passes. The attendant places the bottles on the disk 100 and they are thereby carried through a curved guidewayv formed by the fixed walls 102 toward thesel'ies of rotating bottle supports. By a mechanism 103, which forms nopart of the present invention, the bottlesure then successively wiped off I respective supports. The disk 100 and a friction disk 101 are fixed on a vertical shaft 105, and as the disk 10a is in peripheral contact with the periphery 100 of the rotating disk 1', thedisk -100'is kept continuously rotating. After each bottle has been filled and sealed, its support having nowbeen depressed to its lowest position, the'bottle is wiped off the support onto the table 101 by the deflector 107. I

--In the head f is journaled the drive shaft 108 which, through a worm'109 thereon and worm-wheel 110 on the shaft 54, rotates the latter and through the same, by a pinion 111 on said shaft 54, an intermediate pinion 112 and a gear 113 formed on theidisk' 7', rotates am said disk j; The rack 92 0f the closure diseharging means for the hopper is pivotedto a-fcrank-ll on a shaft 115"s'uitably "jour naled in the head f (Fig. saidshaft being driven :from the diskwj through a 011 transmission shaft 110 suitably gcared'with the disk 100 onto their:

the shaft 115 and said disk (Figs. 1, 22 and 45).

Operation: Upon each bottle being transferred from the receiving disk 100 to a' bottle support It, it is first elevated by its telescoping plunger as the same mounts the rise 17, its mouth,.whatever the height of the bottle, being in that way brought against the corresponding slide 9 (which at this time has been forced by the camwa 97 to its outward position) and thereby initially established at a definite level. After the plunger, having passed over the hump 17, descends to theflevel 17", allowing the bottle mouth to move out of contact with the slide 9 the camway 97 begins to retract the slide. (In the present instance, twelve bottles at a time are proceeding in a circular course around the shaft a. Therefore, for each cycle of movement of the means for conveying the bottles in said course the system of slides 30, 31 and 32 and their adjuncts make twelve complete reciprocating movements, the parts being so timed in t eir action that each movement of said system in one direction is inthe same direction and at the same speed as the bottles, whose movement is a continuous or uninterrupted one). The mouth of the bottle, now projecting into its gasket 21- (right band, Fig. 47), is gripped thereby due to the ring 25 being turned by the camway on the inside of the ring 03' and contracting said gasket in the way already described, whereupon the syrup chargin slide 35 is deglressed 1n the way'explaine the nozzle 58 eing thrust into and against themouth of the bottle and thus causing the charge of syrup in the cylinder to be ejected into the bottle, as stated. It will be understood that in the now ensuing movement of the system of slides 30, 31 and 32 reversely to the bottles the cylinder 55 is recharged. The camway 97'now returns the slide 9 to its outward position, bringing the discharge and of the port 13 therein directly over the mouth of the bottle (left hand, Fig. 47). Meanwhile the fillin -liquid cylinder 69 corresponding to the ottle being referred to is recelving its charge of fillingliquidin the way already explained. Upon the eduction port 08 of said cylinder reachng the channel 64 the filling-1i uid charge in sa d cylinder begins to flow t rough the tube 80 and the port 13 in the slide 9 into the bottle, assisted by the gas pressure, as explained, admitted above the charge in said cy mder through the tubes 82'and78, the air in the bottle escaping via the vent formed bythe'now' registering ports 15 of slide 9 and block 2.- When the whole liquid charge has been transferred from the cylinder 09 tothe bottle the hollow stem of slide 30 (now directly over and advancing with the bottle) is'depressed, sealin the vent (Fig. 48)'-and forming a scale chamber with
